T 0 all whom it may concern:

Be it known that I, KARL A. A. STAAHL- cram, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Inking Mechanism for Bulletin Printing Machines, of which the following is a specification.

This invention relates to improvements in inking mechanisms for telegraph printers of the type disclosed in the patent to Camp bell & Davis, No. 950,473, dated March 1, 1910, in which a large type wheel is rotated partially to bring any desired type into posit-ion to print and operated axially on its shaft to print lateral lines. In order to ink the types on the wheel there is provided an ink reservoir having contacting ink rolls rotated by friction with the wheel. The rapid movements of the wheel, rotary and laterally, cause considerable jerks and shaking' to the inking mechanism which of course moves laterally with the wheel, and means must therefore be provided for maintaining the ink rolls in constant yielding contact with the type wheel.

The object of this invention is to provide an improved inking mechanism having yielding and adjustable means, easily ac cessible, for keeping the ink rolls in contact with the type wheel.

In the drawing illustrating the invention Figure 1 is a rear view of the inking mechanism and Fig. 2 is an end view thereof.

Only so much of the machine is illustrated as is necessary to understand the invention.

The reference numeral 1 denotes a base having upright members as 2 (only one is shown) for the support of the shaft 3 which is preferably squared to facilitate the rotary and lateral operations of the type wheel 4-. The hub 5 of the wheel slides upon the shaft 3 and is provided with a collar 6.

7 is a fork in engagement with said collar. The fork 7 is secured to the upright arm 8 of the carriage 9 which is provided with suitable rolls 10 and 11 which run on the Specification of Letters Patent.

rail 12 supported on the base 1. The carriage and with it the wheel 4: are moved laterally in either direction by a chain 13 operated by any suitable means not shown.

The ink reservoir is marked 14 and contains the contacting ink rolls 15. The reservoir is hung from the carriage 9 by a bracket 16. Because of the rotation of the wheel i a slight play is necessary between the groove -bolt carries a depending wheel bracket 20 in which a roller 21 is journaled and the rollers 21 run upon a track 23 in the base 1.

2% is a spring between the bracket 18 and the wheel bracket 20.

is an adjusting nut on the bolt 14:.

During the operation of the machine the rollers 21 travel on the track .43 and the springs 24! of course tend to lift the ink rolls into yielding contact with the type wheel and prevent tipping of the reservoir and rolls. By turning the nuts 25 the ink reservoir is adjusted to the right position for the ink rolls to touch the type wheel. It will be seen therefore, that by means of the yielding supporting means on each side of the ink box a proper and even inking of the type wheel is assured and that any unevenness caused by the operation of the type wheel in with a large type Wheel and a carriage for Operating the same laterally, of an ink reservoir, ink rolls in said reservoir for inl" ing said type Wheel, a bracket mounted. on each end of said ink reservoir, a squared bolt siidably supported in said bracket, a roller carried by said bolt, an adjusting nut on the latter and a spring. for yieldingly supporting said ink reservoir on the said rollers.

Signed at New York in the county of New York and State of New York, this 18th day of November A. D. 1915.
